830-01 Exam Dumps - RCPE Certified Professional WAN Optimization
A firewall at a remote site on the WAN side of Steelhead appliance (A) is stripping out the 76 and 78 values in the TCP options field. Steelhead appliance (B) is in the local cluster of appliances communicating with an Interceptor appliance. The desired result is for optimization to continue between Steelhead appliance (A) and Steelhead appliance (B) for all traffic originating from the remote site. A suggestion is made to use fixed target rule(s) to meet this objective. Based on the information provided select the best answer from the choices below:
How is peer affinity reset in the CLI for an Interceptor appliance cluster?
Refer to the exhibit.

A data center location has three Steelhead appliances and one Interceptor appliance clustered together. If Steelheads A and B are unable to handle the new web traffic on port 80, the administrator does not want the connection to be serviced by Steelhead C. Given the current rules, we want to prevent traffic from redirecting to Steelhead C.
Current Rules:
Rule 1: Redirect rule for ports 445, 139, 80, target SH A
Rule 2: Redirect rule for ports 8080, 80, target SH B
Auto (default rule)
Which rule should be added on the Interceptor to achieve desired functionality?

A customer wants to optimize traffic from remote VPN sites to DMZ servers in the data center shown in the accompanying exhibit.
The customer would also like to deploy their data center Steelhead appliance in a way that would allow them to keep transparency to the LAN servers, and allow the LAN servers to initiate optimized connections to remote sites. The current network architecture can satisfy these requirements by using which following deployment method?
In a Steelhead deployment, the customer decides to use Full Transparency and block all incoming/outgoing TCP connections on port 7800 on their firewall. However, they are finding all TCP connections are passing through the Steelheads (even ones that should be optimized via the in-path rule set).
If Full Transparency uses the original IP addresses and TCP ports for inner connections, what is needed to fix the problem?
You are configuring HighSpeed TCP in an environment with an OC-3 (155Mb/s) and 60 milliseconds of round-trip latency. You know that the rule of thumb is to set the WAN router queue length to BDP for the link. Assuming 1500 byte packets, the queue length for this link would be closest to: (Hint: Use the calculator)
Place the following commands to upgrade a Steelhead appliance from the CLI in the correct order. (NotE. include only the necessary steps)

What is the supported redirection scheme/s used when a Steelhead appliance is in a WCCP deployment?
The Primary interface is REQUIRED for which deployment methods and features?
1) In-path
2) Server-side out-of-path
3) Logical in-path (WCCP/PBR)
4) Hybrid Mode
5) Proxy File Services (PFS)
Refer to the exhibit.
In order to achieve optimization using auto-discovery for traffic coming from site C and destined to site A in the exhibit, which configuration below would be required?
When using Correct Addressing, without Enhanced Auto-discovery (EAD), what is the size of the probe response in the return SYN/ACK packet from the server-side Steelhead appliance?
The Home page in the Management Console for the CMC appliance can be configured to display what information?
Refer to the exhibit.
You noticed the following entry in the logs. What is the cause of the problem?
Refer to the exhibit.
A connection times out when Client41 and Client42 attempt to either establish an HTTP session to Server31 or an FTP connection to Server32 after not connecting to them for some time. The very next attempt to connect to these services done immediately after the failure seems to work correctly. The clients are able to ping both servers and no access-lists are configured on the routers. SH3 uses the IP address of R3f0 as its default gateway. Upon powering off SH3 and SH4, the problem goes away even for first connection and everything works normally (even after not connecting for extended periods of time). Which of the following are likely to correct this problem?
Refer to the exhibit.
Corp-A and Corp-B have overlapping address space and therefore the network administrator implemented NAT to overcome this. Users from Corp-A NAT to 172.16.1.0/24 and users from Corp-B NAT to 172.16.2.0/24. Users in Corp-A use the destination address of 172.16.2.0/24 to access the resources in Corp-B. The servers in Corp-B use the client IP for authentication. You deploy the Steelhead appliance using the default WAN visibility mode but noticed all the connections are passed-through. What is the likely problem?
What Steelhead appliance models support the installation of Microsoft Windows Server 2008 R2 package on the RSP? (Select 2)
In an in-path deployment, if a naked SYN packet arrives on the WAN interface of Steelhead, what probe option is added to this SYN packet for auto-discovery?

A customer already has a SteelHead appliance in their datacenter and wants to add Steelhead Mobile. Their current deployment has their VPN gateway in parallel with their server-side SteelHead. The customer doesn’t want to interrupt VPN clients by moving the SteelHead in-path with the VPN gateway, so they will test using a fixed-target rule to the SteelHead in-path interface. Take a look at this diagram:
